To take care of a baby turtle, you need an aquarium. Fill it with water, deep as the turtle is wide. Place some rocks in there for ‘land’. You can buy turtle food from the pet store. They also need to eat earthworms, greens and fruits. Make sure to keep their house clean by removing old food that remains, cleaning the aquarium water, and rinsing him off with warm water to remove any food that may be left on him.
